Call it a lesson in specificity. I’m sure when the New Urbanists talked about “mixed use” they weren’t considering airports. The Economist reports on Mesa, Arizona’s city of the future:
The forward-looking part of the plan is that Mesa will be built around an airport. Rather than pushing air traffic to the fringe of the city, as most cities try to do, Mesa will build around its runways. It hopes to become what John Kasarda of the University of North Carolina calls an “aerotropolis”—a city as tied to air traffic as 19th-century cities were to railways.
It is one thing to recognize the economic opportunities of a major airport, but quite another to make the airport your downtown. This strikes me as a Corbusian scheme without regard for the human element.
